AMAZILIA. 299 
Hab. Mexico, Santa Efigenia, Tehuantepec (Ff. Sumichrast !*). 
The only specimen we have seen of this distinct species was sent by the late 
Prof. F. Sumichrast to M. Boucard and ceded to us by him. The specimen is a male, 
and was shot in December 1877. It is named after its discoverer, who long resided at 
various places in South Mexico and studied the vertebrate fauna of that country with 
great industry and success. 
A. sumichrasti has some resemblance to A. ocai, but the points of difference are 
many and obvious. Chief amongst them is the colour of the under tail-coverts and 
tail, and the denser green colour of the throat, on which the white bases of the 
feathers are hardly visible.

Hab. Mexico, Yucatan (Cabot!?), Merida in Yucatan (Ff. D. G.°, G. &. Gaumer °); 
GuaTEMALA, Santa Ana in Peten (0. S. 7). 
Dr. Samuel Cabot, who accompanied Stephens in his well-known travels in Yucatan, 
was the discoverer and describer of this species. His type also formed the subject of 
the plate in Gould’s Monograph of the Trochilide, the upper figure of which, supposed 
to represent a female of this species, was drawn from a specimen of A. cinnamomea, as 
Gould more than half suspected at the time. 
Many years elapsed after the first discovery of this species before anything more 
was heard of it, and it was not until Salvin shot three specimens at the little village of 
Santa Ana, on the road from Vera Paz to Peten, in April 1862, that it was again 
noticed. Since that time a few more examples have reached us from Northern Yucatan, 
amongst them two males which were shot by Godman when at Merida in February 
1888. 
The Santa Ana birds were feeding from the flowers of an Erythrina in company with 
Amazilia riefferi and Lampornis prevosti.
